The feeling like the razor sharp noise of a fan blade scraping across the inner surface of your scull. Hallowing out a cavity. Leaving a space for those wintery cold thoughts to ice over inches above the current, solidify themselves, just the same as the concrete numbness in one who feels frozen feet but remains trembling at the spine. A shivering transference of short circuiting energy and no wonder your hands shake so balancing on pins and needles. Wobbly knees. Graceful feathered voice.
